| Abstract: | This paper look at the utilization of industrial by-products (IBPs) as aggregate for roadway sub-base construction for the Pittsburgh, Pennsylvania, urban region. The scenarios compare the use of virgin aggregate with the use of combination of both virgin and IBP aggregate, where the aggregate material is selected based on proximity to the construction site and allows for minimization of transportation impacts. The results indicate that the use of IBPs to supplement virgin aggregate on a regional level has the potential of reducing impacts related to energy use, global warming potential, and emissions of nitrogen oxides, sulfur dioxide, carbon monoxide, PM10, mercury and lead. |
